program to make cd work like a floppy?

I want to backup my Quicken data onto a CD, but it only gives me the option to backup onto a disk disk (now 8 disks to backup). The help menu says I can do it, but I need some software that will allow me to treat my CD drive like a floppy drive. Is anyone familiar with this type of software? Can I download it from somewhere like www.downloads.com ? Thanks.
